Database Functions is a class to build and execute
MySQL database queries. It can build SELECT,
INSERT, UPDATE, and DELETE queries from lists of
parameters and values. The class can also execute
the generated queries and retrieve the SELECT
query results into associative arrays.

DooPHP is a very fast PHP framework. It enables developers at all levels to rapidly develop robust Web 2.0 applications. It is quite feature rich. DooPHP supports some common stuff found in a Web framework, such as an MVC-base structure, RESTful APIS, a REST client, URI routing, database ORM tools, a model generator, HTTP Digest Authentication, a flexbible compiling template engine, logging and profiling tools, and more.

NaturePHP is a classes wrapper using PHP's autoload to create a non-intrusive, simple, organized, and extensible library system. It is aimed at intermediate and advanced PHP developers, providing a lot of non-intrusive functionality for Web site and application development. Upcoming development will include internal library management and the ability to download/update libraries from the repository.

Mysql Done Right is a PHP 5.0+ class that provides a safe, clean, object-oriented, and efficient way to do database development. All queries except those with multiple row results return exactly what you need in one line of code. This is all done while still maintaining use of prepared queries and bound parameters to eliminate the risk of SQL injection attacks and operate more efficiently. No extra coding is needed on your part to reuse prepared queries. You simply write the same query again, and if you have used that one before, the prepared handle is reused. The newly bound parameters are used against the existing prepared handle, and the results are recomputed. The results themselves are not cached. Database connectivity is implemented using MySQLi.

Dominion v8 is a PHP universal database abstraction layer to develop rapid portable and compatible applications connecting to any freeware or commercial databases. You no longer need to write proprietary SQL sentences, but can use portable objects that give you the power to change the database engine without rewriting a single line of code.

DALMP is a MySQL abstraction layer for PHP. It includes memcached support and a simple database session store. Common methods have the same name as those in ADOdb to ease integration with existing code.

minidb is a Python module that utilizes the SQLite3 database library in order to store and retrieve Python objects. It utilizes Python's __slots__ mechanism to determine the column names, and uses the class name for table names. Data is always stored as text in the database, but will be converted using the type specified in __slots__ (which therefore has to be a dict).

This project provides a minimal extension for PHP's PDO (PHP Data Objects) class. It is designed for ease-of-use and reducing development time and effort. This is achived by providing methods - delete, insert, select, and update - for quickly building common SQL statements, handling exceptions when SQL errors are produced, and automatically returning results and number of affected rows for the appropriate SQL statement types.

Moqui Framework is a seamlessly integrated, enterprise-ready framework for building enterprise automation applications based on Java. It includes tools for database interaction (relational, graph, document), logic in local and Web services, Web and other UIs with screens and forms, security, file/resource access, scripts, templates, localization, caching, logging, searching, business rules, workflow, multi-tenancy, and integration.

Relational Ètudes (re, for short) is an implementation of the relational model. Written in PHP, re can be considered a PHP Framework. Specifically, re tries to implement the ideas presented in the book "Databases, Types, and the Relational Model" (The Third Manifesto). As such, re is based on a rigorous scientific theory, and thus has wider applicability. For instance, from a Model-View-Controller (MVC) approach in software development, re can be considered as the "Model" component. It is even possible to implement your own MVC-type framework using re as its main foundation. re has a consistent and intuitive application programming interface (API). Relational operators are supported, thus, data/set manipulation is simplified. Applications using re will be easy to maintain and extend. Distributed data can be easily used. Business rules are cleanly implemented. It should be very easy to integrate re in your projects, since it is designed to be framework agnostic.
